Sen (pronounced Shen) is a Bengali Hindu surname derived from the Sanskrit word for "Army", Sena.
It is found in the east of the Indian Subcontinent; namely Bangladesh & West Bengal, India mainly among Baidya and Kayastha communities. Instances of the surname are also found in the Nepalese community.
The Meghna River (Bengali: মেঘনা নদী) is one of the most important rivers in Bangladesh, one of the three that forms the Ganges Delta, the largest on earth fanning out to the Bay of Bengal. Being a part of the Surma-Meghna River System, Meghna is formed inside Bangladesh by the joining of different rivers originating from the hilly regions of eastern India. The river meets Padma River in Chandpur District. The river ultimately flows into the Bay of Bengal in Bhola District.
Major tributaries of the Meghna include the Dhaleshwari River, Gumti River, and Feni River. The Meghna empties into the Bay of Bengal via four principal mouths, named Tetulia (Ilsha), Shahbazpur, Hatia, and Bamni.
The Meghna is the widest river among those that flow completely inside the boundaries of Bangladesh. At one point near Bhola, Meghna is 12 km wide. In its lower reaches this river follows almost a straight line in its path. Despite its very calm and quiet look, this river is the cause of many deaths every year. Several ferry and launch sinkings in the past have killed hundreds, like the MV Salahuddin-2 and the MV Nasrin-1. Near Chandpur it is very dangerous.
